5. Either: • Map the volumes to the host by setting a starting LUN, selecting ports, and setting access to read-only or read-write. • Mask the volumes from the host by setting a starting LUN, selecting ports, and setting access to no-access. 6. Click Apply. A message specifies whether the change succeeded or failed. 7. Click OK. Changing a volume's default mapping CAUTION: Volume mapping changes take effect immediately. Make changes that limit access to volumes when the volumes are not in use. Be sure to unmount/unpresent/map a volume before changing the volume's LUN. NOTE: You cannot map the secondary volume of a replication set. NOTE: When mapping a volume to a host using the Linux ext3 file system, specify read-write access; otherwise, the file system will be unable to mount/present/map the volume and will report an error such as "unknown partition table." To view the default mapping In the Configuration View panel, right-click a volume and select Provisioning > Default Mapping. The main panel shows the volume's default mapping: • Ports. Controller host ports through which the volume is mapped to the host. • LUN. Volume identifier presented to the host. • Access. Volume access type: read-write, read-only, not-mapped. To modify the default mapping 1. Select Map. 2. Set the LUN and select the ports and access type. Setting the default mapping to no-access will result in the LUN mapping being removed. 3. Click Apply. A message specifies whether the change succeeded or failed. 4. Click OK. Each mapping that uses the default settings is updated. To delete the default mapping 1. Clear Map. 2. Click Apply. A message specifies whether the change succeeded or failed. 3. Click OK. Each mapping that uses the default settings is updated. 64 Provisioning the system

Provisioning the system
5.
Either:
•
Map the volumes to the host by setting a starting LUN, selecting ports, and setting access to
read-only
or
read-write
.
•
Mask the volumes from the host by setting a starting LUN, selecting ports, and setting access to
no-access
.
6.
Click
Apply
. A message specifies whether the change succeeded or failed.
7.
Click
OK
.
Changing a volume’s default mapping
CAUTION:
Volume mapping changes take effect immediately. Make changes that limit access to volumes
when the volumes are not in use. Be sure to unmount/unpresent/map a volume before changing the
volume’s LUN.
NOTE:
You cannot map the secondary volume of a replication set.
NOTE:
When mapping a volume to a host using the Linux ext3 file system, specify read-write access;
otherwise, the file system will be unable to mount/present/map the volume and will report an error such as
“unknown partition table.”
To view the default mapping
In the Configuration View panel, right-click a volume and select
Provisioning > Default Mapping
. The main
panel shows the volume’s default mapping:
•
Ports. Controller host ports through which the volume is mapped to the host.
•
LUN. Volume identifier presented to the host.
•
Access. Volume access type: read-write, read-only, not-mapped.
To modify the default mapping
1.
Select
Map
.
2.
Set the LUN and select the ports and access type. Setting the default mapping to
no-access
will result in
the LUN mapping being removed.
3.
Click
Apply
. A message specifies whether the change succeeded or failed.
4.
Click
OK
. Each mapping that uses the default settings is updated.
To delete the default mapping
1.
Clear
Map
.
2.
Click
Apply
. A message specifies whether the change succeeded or failed.
3.
Click
OK
. Each mapping that uses the default settings is updated.
